Your Laser Vision Surgery

LASIK Candidate


The Initial NVISION Consultation:  What can I expect?

At NVISION, your initial consultation will consist of an examination of your eyes to determine your unique condition as well as an overview of the laser procedures available to treat your condition.  The exam consists of measuring the dimensions and properties of your untreated eyes using techniques such as wavefront analysis and topographical mapping as well as diagnostic instruments such as a pachymeter or an Artemis.  From these measurements, the doctor can determine the precise amount of LASIK correction needed.

What can I expect to happen in my laser vision correction?

There are three phases of laser vision correction procedure:  the pre-procedure consultation, the laser procedure, and the post-procedure care.  Two doctors are involved in the overall procedure:  the NVISION surgeon who performs the procedure at the NVISION center and your own eye doctor who can provide your pre- and post-operative care.  Your pre- and post-operative care can also be provided at NVISION if you do not have your own eye doctor. 

All doctors working with NVISION, including your own eye doctor, have been educated in laser vision correction.  NVISION recommends that you consult with your own eye doctor who is familiar with your eye history and will continue to care for you years after your procedure.  NVISION doctors and staff work closely with your eye doctor to ensure the highest level of care and results.

What happens during the laser vision correction surgery?

During LASIK vision currection surgery, an exceptionally thin and accurate flap of corneal tissue from the surface of the eye is cut but is not removed. It remains anchored on one side, allowing the surgeon to replace it in its identical position once the LASIK procedure is complete.  When the corneal flap is raised, the excimer laser sculpts the bed of the cornea to match the dimensions determined before the surgery.  The surgeon replaces the corneal flap, and within minutes, the eye naturally holds the flap in place, and the LASIK procedure is complete.  Within a few hours after the procedure, the surface of the cornea starts to grow over the cut edge of the corneal flap and to seal it into position.  Top surface healing is complete within a week, and the underlying surface will heal within three months.

Where is the surgery done?

The surgery is done at the NVISION center of your choice.  All the NVISION centers have state-of-the-art lasers and experienced doctors, many of whom have performed more than 10,000 LASIK procedures.

How long does the surgery take?

Laser vision correction surgery takes about 10 minutes per eye, and you are only under the laser for seconds.  Preparation for the surgery takes 30–60 minutes.  Expect to be at your NVISION center for 2–3 hours on the day of surgery.

What if I look away, blink, cough or sneeze during the procedure?

The outcome of your procedure will not be affected if you look away, blink, cough, or sneeze during the surgery.  The tracking device on the laser tracks microscopic movements. If any gross movements occur, the laser stops, and once the eye is repositioned properly, it starts up again where it left off.

What do I need to do to prepare on the day of surgery?

Do not wear your contact lenses.  Do not wear make-up for a minimum of 24 hours before surgery.  Arrange transportation as you will not be able to drive yourself home.  Avoid alcohol 24 hours before and 48 hours after surgery, as it tends to dehydrate your eyes.  Avoid caffeine the morning of your surgery.  Do not use perfumes or cologne or any other products that contain alcohol.  Wear comfortable clothing, and get ready to see clearly.

Does LASIK surgery hurt?

Most patients find the procedure to be slightly uncomfortable.  Anesthetic drops are used to numb the eye before surgery begins, and you may be given a mild sedative.  After your procedure, your eye may feel a foreign-body sensation or irritation (mild burning sensation) for a few hours, but most patients are quite comfortable after taking a short nap.  You will be given drops for your eyes to address the potential dryness you may experience for several weeks following the surgery.

The best way to understand how LASIK surgery feels is to talk with someone who has had the procedure.  For most patients, the feeling of anxiety and fear of the unknown is worse than the actual procedure. 

Are the lasers used in laser vision correction procedures safe?

NVISION uses only FDA-approved lasers to gently reshape the cornea during LASIK.  These excimer lasers use cool, computer-controlled beams of ultra-violet light.  NVISION doctors have performed hundreds of thousands of successful LASIK surgeries with their state-of-the-art, FDA-approved lasers.
